Array Substrate, Driving Method and Display Device

摘要

There are disclosed in the present disclosure an array substrate, a driving method of a fingerprint recognition circuit and a display device. The array substrate comprises a substrate. There are formed on the substrate a fingerprint recognition circuit, a fingerprint signal read line, an initialization signal line, a common voltage input terminal and an output control signal line. As such, on one hand, since it is not needed a separate film layer or panel to carry the fingerprint recognition circuit, thickness of a corresponding display device can be reduced; on the other hand, the fingerprint recognition circuit and related signal lines can be formed simultaneously in the process of manufacturing the array substrate, thereby decreasing difficulty in manufacturing the corresponding display device.
